8/10. Scriptwriter Jerome Bixby's first draft had Flint as having been Jesus, Moses and Pablo Picasso. NBC's Broadcast Standards did not want Jesus or Moses mentioned for fear of public outrage. Picasso was also dropped because he was alive at the time of this episode's first broadcast. According to researcher Joan Pearce, "attributing a fictitious work of art to a living artist can bring legal repercussions."
Rayna Kapec is named for Czechoslovakian writer Karel Capek who first coined the term robot in his classic science-fiction play R.U.R.
Flint's castle was the reused matte painting of the Rigel VII fortress in "The Cage." In the terrific remastered episode an entirely new castle was created.
The undercarriage of Flint's M-4 robot is a reused section of the upper carriage of Nomad from "The Changeling."
In the ST: TNG episode "The Offspring" Lal, an android created by Lt. Cmr. Data, also dies after she is overwhelmed by experience and love.

"Constantinople, Summer 1334. It marched through the streets, the sewers. It left the city by oxcart, by sea, to kill half of Europe. The rats, rustling and squealing in the night as they, too, died. The rats..."

I was flawed on #9.
